Fuel Injector Seal (Fuel Injector Retaining O-ring), Large, 1975-80 VW Beetle and Super Beetle, 1975-92 VW Bus and Vanagon, 1968-74 Type 3, and 1975-76 Porsche 914, EACH, 311-133-263 slips around a thin part of the injector, allowing the clamp to hold it! You need 1 of these for EACH injector, don't forget the small injector seal between the injector and intake manifold!

Barrel Clamp, Accelerator Cable and Heater Box Cable, 8 x 12mm, EACH, 111-129-921-311-129-777 are used at the stock carburetor to throttle cable, and at the heater cable to heater box lever. These often get lost or damaged, having spares is a good idea!

Barrel Clamp, Accelerator Cable and Heater Box Cable, Flat Blade Head, 8 x 12mm, 311-129-777 is used at the stock carburetor to throttle cable, and at the heater cable to heater box lever. These often get lost or damaged, having spares is a good idea! This version with the flat blade head is preferred by many because they can quickly tighten or loosen it with a screwdriver, instead of finding that pesky 8mm wrench!

5/16" Hose Clamp, Band Style, EACH, HCM-6F is great for vw fuel hose, both FI or carbureted. The band style prevents the clamp from cutting into the hose, which is a problem with traditional worm gear style clamps! These are the best clamps to use.

Rubber Mounting Damper, 6 x 1mm Thread, EACH, 9259-7 is often used to eliminate vibration from vibrating electric fuel pumps, or external oil coolers. This uses a 10 x 1mm stud on either end, for easy mounting! These have more uses than you think! Sold per EACH.

O2 Sensor Plug, Mild Steel (18 x 1.5mm Threads) is designed for you to plug the threaded bung up when you don't have the O2 sensor installed for whatever reason (IE: You are finished tuning). You can save wear/tear on the O2 sensor by saving it!

These often get lost or damaged, having spares is a good idea! This version with the flat blade head is preferred by many because they can quickly tighten or loosen it with a screwdriver, instead of finding that pesky 8mm wrench!

7mm Hi Pressure Fuel Hose (Fuel Injection), 7.0 X 3.0mm, per Meter, N202811 is a HIGH PRESSURE hose compatible with the higher fuel pressures seen in FI systems. This is a smooth rubber hose that is easy to clean and lasts for years.

You can also use this outstanding hose on 7mm carbureted applications if you prefer the look of smooth rubber instead of the normally used cloth braided hose.

O2 Sensor Bung and Plug, Mild Steel (18 x 1.5mm Threads) is designed for you to weld to your exhaust system to repair or install an O2 sensor to FI closed loop operation, or for detailed wideband tuning.

O2 Sensor Bung and Plug, Stainless Steel (18 x 1.5mm Threads) is designed for you to weld to your exhaust system to repair or install an O2 sensor to FI closed loop operation, or for detailed wideband tuning. Stainless Steel for SS exhausts!

Intake Manifold Gasket, Fuel Injected Type 1 (1975+), Each, 043-129-707 prevent the head from the cylinder heads from overheating the fuel injectors. These often crack when removed, so replacement is recommended.

If you have an injected car, this book is a MUST. Extensive chapters on FI theory, and exceptional troubleshooting procedures. Complete theory, troubleshooting, service, and high performance tuning of Bosch fuel injection systems. Includes Motronic, L-Jetronic, KE-Jetronic, K-Jetronic and D-Jetronic systems. This is the ONLY book that fully explains how Bosch systems work and how to get the most out of racing and high performance tuning modifications.

Engine Temperature Sensor (Fuel Injection Sensor), 1975-79 Type 1, 1977-83 Type 2, and 1970-73 Type 3, 022-906-041A (replacement for Bosch 0-280-130-012) signals the fuel injection computer what temperature the engine is at, and it makes the corresponding mixture adjustments! These often go bad, and result in a very rich running condition, because the computer "thinks" the engine is perpetually cold!

Fuel Injector, Rebuilt, 1975-79 Beetle and Super Beetle, 0-280-150-112 are the finest rebuilt fuel injectors we have found anywhere. We always recommend replacing all 4 in a matched set, so you do not wind up with fuel injectors of different flow rates on the same engine.

Innovate Wiring Harness Extension, 18', Fits LC-2, LM-2 and MTX-L, PRIOR TO 2/15/15, for use with 4.2 O2 Sensor, 3828 is for people that have the Innovate LC-2, MTX-L Gauge or Innovate LM-2, with the 4.2 O2 Sensor, but have a rear engined car! The harness that comes with the gauge is too short, so we had this one made! It's 18' long and will allow you to use your new Wideband toy!. This will allow you to use the LM-2 and MTX-L systems in all Rear and Mid-Engined VW and Porsche cars. Vanagons, Busses, 911s, Beetles, Ghias, etc. This does NOT fit the 4.9 O2 Sensors!

Fuel Injection Intake Boot, 1975-79 Type 1 With Stock Fuel Injection, 043-129-617A-043-617A is a commonly cracked part on the stock fuel injection. These are VERY OFTEN cracked and the cause of erratic idling and stalling when hot.

Thermo Time Switch, 1976-79 Type 1 and 1976-83 Type 2, EACH, 0-280-130-214 tells the FI computer how cold it is out and how long the engine has been running, so the computer can use the proper fuel map for the current conditions.

Fuel Pump Relay (Double Relay), 1975-79 Beetle and Super Beetle, 1975-83 Type 2, 0332514120 replaces that black box which is either not turning the fuel pump on, or which fails to turn it off when you turn the key off (running your battery down!).

Innovate Wiring Harness Extension, 18', Fits LC-2, LM-2 and MTX-L, AFTER 2/15/15, for use with 4.9 O2 Sensor, 3889 is for people that have the Innovate LC-2, MTX-L Gauge or Innovate LM-2, but have a rear engined car! The harness that comes with the gauge is too short, so we had this one made! It's 18' long and will allow you to use your new Wideband toy!. This will allow you to use the LM-2 and MTX-L systems in all Rear and Mid-Engined VW and Porsche cars. Vanagons, Busses, 911s, Beetles, Ghias, etc.

Fuel Pressure Regulator, (Fuel Injection Engines), 1975-79 Type 1, and 1977-83 Type 2, (Replacement for Bosch 0-280-160-200) adjusts the fuel pressure based on load via a vacuum reading from the Intake Plenum. When these go bad they leak internally, or the pressure is wrong! Remove the vacuum hose, if you see fuel the diaphragm is shot! The pressures for testing are in the Bentley Manual. You can tee in a pressure gauge to check the pressures.

Fuel Pump, Stock Fuel Injection, NEW, 1975-80 VW Beetle and Super Beetle, and 1975-92 VW Bus and Vanagon, and 1975-76 Porsche 914, 251-906-091 is a fantastic replacement fuel pump, for less than 1/2 of the Genuine Bosch Price, and we feel they are as good as Bosch! These are NEW, not rebuilt, for a long life. It's very important on Fuel Injected vehicles to never run out of fuel, because the gasoline is the coolant for the fuel pump! If you run out, the pump overheats and will die quickly!

Auxiliary Air Valve, 1975-79 Type 1 and 1976-83 Type 2, 0-280-140-101 is the item that increases air flow when the engine is cold, for a faster idle and faster warm up. When these go bad they stick closed when cold (engine stalls or idles very slow), or open when hot (racing idle when hot).
